I'm glad you posted this! I've been having the sensation odd misplaced sounds recently too. I've never categorized them as hallucinations though and I don't have a word for it. Even though I do experience music, voices, and a radio as examples of hallucinations it takes me a long time to realize what they are. With the sounds I need a few seconds too realize that my kids are in front of me but it sounds like they're beside me and a distance away.
I also have noticed that things can be distorted. If someone says something it can sound like a growl from a monster or other weird this. These aren't things I've ever had a doctor bring up and I haven't read about it before but it's happens 10-15 times a day and comes on bursts through the year.
I did have the theory that because they are real and true sounds being misheard it may stem from my irritating fall allergies.
